  • Patent number: 11911996
    Abstract: Methods and apparatus for modulating light using a tunable light modulation device. The tunable light modulation devices comprises an elastomer structure including at least one elastomer layer, a compliant electrode network of conducting fibers arranged on a first surface of the at least one elastomer layer, a patterned electric conductor arranged on a second surface of the at least one elastomer layer opposite the first surface. The patterned electric conductor includes a plurality of individually-addressable sections, and the compliant electrode network is configured to compress the at least one elastomer layer in the presence of an electric field between the compliant electrode network and one or more of the individually-addressable sections of the patterned electric conductor to produce a voltage-dependent roughening of the at least one elastomer layer.

  • Patent number: 11674213
    Abstract: Some embodiments provide a magnetron sputtering apparatus including a vacuum chamber within which a controlled environment may be established, a target comprising one or more sputterable materials, wherein the target includes a racetrack-shaped sputtering zone that extends longitudinally along a longitudinal axis and comprises a straightaway area sandwiched between a first turnaround area and a second turnaround area, a gas distribution system that supplies a first gas mixture to the first turnaround area and/or the second turnaround area and supplies a second gas mixture to the straightaway area, wherein the first gas mixture reduces a sputtering rate relative to the second gas mixture. In some cases, the first gas mixture includes inert gas having a first atomic weight and the second gas mixture includes inert gas having a second atomic weight, wherein the second atomic weight is heavier than the first atomic weight.

  • Patent number: 11454440
    Abstract: The invention provides an IG unit comprising two panes and a between-pane space located between the two panes. A desired surface of a selected one of the two panes bears a coating comprising both a transparent conductive oxide film, and an overcoat film located over the transparent conductive oxide film. The IG unit further comprises a bus bar and a transparent conductor bridge each located over the desired surface. The bus bar is spaced apart from the coating and is connected electrically to the transparent conductive oxide film by virtue of the transparent conductor bridge extending from the bus bar to a top surface of the overcoat film. In some embodiments, the IG unit further comprises a frit located over the desired surface and extending around a perimeter thereof. The bus bar is located over the frit. Certain embodiments provide a refrigerator having a door comprising such an IG unit.

  • Patent number: 11340479
    Abstract: The invention provides an elastomeric optical device having a first optical state and a second optical state. The device is transparent when in the first optical state and translucent or opaque when in the second optical state. The device comprises, in sequence, a first transparent electrode, a dielectric layer, an elastomer layer, and a second transparent electrode. The elastomer layer preferably has certain mechanical properties, such as a Shore OOO hardness of less than 15, and/or certain chemical properties, such as being substantially devoid of unreacted sites. The second transparent electrode is configured to compress the elastomer layer in response to an electric field between the first and second transparent electrodes, such that when the elastomeric optical device is in the second optical state, the elastomer layer is compressed between the first and second transparent electrodes. Methods of operating an elastomeric optical device are also provided.
